After sifting through hundreds of tips, detectives have closed three crimes featured in Crack the Case, and have a felony warrant in connection to another.

The felony warrant is for 17-year-old Arthur Jacob Campbell. He is believed to be the suspect who pulled a large knife on a lone female clerk at the Speedway gas station at 1215 S. Saginaw Road on Aug. 9.

Anyone with information on Campbell's whereabouts is asked to contact Midland Police Detective Robert Brzak at (989) 839-4709.

Closed cases include two investigated by police Detective Caryn Weiland. The first case to be solved was the theft of sneakers from Kohl's, when the suspect recognized his photo in an August issue of the Daily News and turned himself in. He was sentenced in the Midland County District Court in the fall to serve 90 days in jail with credit for 28 days.

On Christmas, the suspect in the June 6 feature about a woman who used stolen credit cards to buy items at stores along Eastman Avenue as well as in Lansing was arrested in Taylor. Weiland also is close to solving the case of a man who used stolen credit cards to buy items at Meijer, featured in a May 20 story. She said he does not live in Michigan, but was staying with residents when the crimes were committed.

Midland County Sheriff's Detective Lt. Vincent Szilagyi reported the suspect in the use of a stolen credit card at a Sanford gas station and stores at the Midland Mall also was caught after the victim viewed surveillance video.

Szilagyi said the victim thought he lost the cards while he was on the Pere Marquette Rail-Trail, but later realized they fell out of his pocket when he was given a ride home by the suspect shown using the card in the video. The 18-year-old female suspect was arrested.
